A square has a side length of 10cm. Work out the length of a diagonal of the square.​

Answer:

no

Step-by-step explanation:

Answer:

If you want a simple average, you can add all the speeds you see and divide them by the number of how many they are.  

So firstly you have to calculate the speed of the first point, which is:  

20 miles/0.5 hour

That means: 40 miles/hour

That would be your first "speed"

Then you calculate all of them :speed1+speed2+speed3 = something.  

As an example: 20miles/hr + 40miles/hr+0miles/hr = 60miles/hr

Then, you divide it by how many "speeds" they are: 60miles/hr divided by 3 if I continue my previous example.

It is my first answer, and I hope I could help you a bit!

Sorry for the awkward English, as it is not my mother tongue.

Answer: well

Step-by-step explanation:

The answer is 37.68

We need to find the area of the sector of the circle.

There is a missing part in the upper left part of the circle.

The upper left part central angle measure 90 degree becuase it has a perpendicular sign.

Using central angle and arc theorem, the central angle equal the arc measure so that arc measure is 90 degrees.

There is 360 degrees in a circle so using arc addition,

the rest of the arc measure 270 degrees.

We can use this formula to find the area of the sector

[tex] \frac{x}{360} \times \pi \times {r}^{2} [/tex]

where x is the measure of the central angle and r is the radius.

Plug 270 in for x. The radius is 4.

[tex] \frac{270}{360 } \times \pi \times {4}^{2} [/tex]

[tex] \frac{3}{4} \times \pi \times 16[/tex]

[tex]12\pi[/tex]

Answer:

x = [tex]\frac{16}{3}[/tex]

Step-by-step explanation:

Since the triangles are similar then the corresponding sides are congruent.

EF and BC are corresponding sides , then

8x - 3 = 5x + 13 ( subtract 5x from both sides )

3x - 3 = 13 ( add 3 to both sides )

3x = 16 ( divide both sides by 3 )

x = [tex]\frac{16}{3}[/tex]

Answer:

[tex]Volume = 643.0\ in^3[/tex]

Step-by-step explanation:

Given

Dimension: 4.75in, 4.75in and 28.5in

[The complete dimension is missing from the question]

Required

Calculate the volume

The volume is calculated as thus:

[tex]Volume = 4.75in * 4.75in * 28.5in[/tex]

[tex]Volume = 643.03125in^3[/tex]

[tex]Volume = 643.0\ in^3[/tex] --- approximated

Step-by-step explanation:

I plugged it in the calculator. And then they both were zero.

Answer:

x = 2

Step-by-step explanation:

f(x) = x + 8

f(x) = 10

10 = x + 8

minus 8 from the both sides

10 - 8 = x

2 = x

x = 2

Hope this is right correct me if im wrong!!!

Exponential function is a function between the dependent variable and independent variable in which the constant change in the independent variable gives the same proportional change in the dependent variable.

[tex]y=\dfrac{10}{3} \times 3^x[/tex]

Given information-

The exponential function [tex]f[/tex] takes the value 10 when,

[tex]x=1[/tex]

The exponential function [tex]f[/tex] takes the value 2 when,

[tex]x=2[/tex]

Exponential function is a function between the dependent variable and independent variable in which the constant change in the independent variable gives the same proportional change in the dependent variable.

The general form of the exponential function,

[tex]y=ab^x[/tex]

Here [tex]a[/tex] is the y intercept of the function and exponent of independent variable [tex]x[/tex].

The exponential function [tex]f[/tex] takes the value 10 when the value of x is 1.

thus,

[tex]10=ab^1\\10=ab\\a=\dfrac{10}{b}[/tex]

Let the above equation as equation number 1.

The exponential function [tex]f[/tex] takes the value 2 when the value of x is 2,

[tex]30=ab^2\\30=ab^2\\a=\dfrac{30}{b^2}[/tex]

Compare the values of a,

[tex]\frac{10}{b} =\frac{30}{b^2}\\ b=\dfrac{30}{10}\\ b=3[/tex]

Put the value of b in equation 1,

[tex]a=\dfrac{10}{3}[/tex]

Thus the y intercept of the function is 10/3.

Put the values to find the equation,

[tex]y=\dfrac{10}{3} \times 3^x[/tex]

Hence,

[tex]y=\dfrac{10}{3} \times 3^x[/tex]

Hope this helps. I recommend the website wolfram alpha.

Answer:

x = 1

Step-by-step explanation:

The proportion in this question is (3z) : (3z)+(z+22) = (2x+1) : (8x-2), since there are two triangles that are similar.

The question said that 3z = z+22

--> 2z = 22

--> z = 11

So our new proportion will be:

--> (3z) : (3z)+(z+22) = (2x+1) : (8x-2)

--> (33):(66) = (2x+1):(8x-2)

--> (66)(2x+1) = (33)(8x-2)

--> 132x + 66 = 264x - 66

--> 132x - 132 = 0

--> 132x = 132

--> x = 1
